UX & UI Design Sydney

UX & UI Design in Sydney

User experience and interface design for Sydney businesses, from our studio in Penrith. We find out where your customers get stuck, then design websites, stores and apps that feel obvious to use and quietly lift conversions.

Design + build One team, nothing lost in handover

Sydney customers have plenty of choice, and they are quick to leave a site or app that makes them think too hard. A confusing menu, a form that asks for too much, a checkout with one step too many: each one costs you enquiries you never hear about. UX design is how you find and fix those leaks, and UI design is how you make the result look as good as it works.

We are a Western Sydney team based in Penrith, working with businesses across Greater Sydney. That means workshops in person when they help, and a designer who understands the local customers you are trying to win.

Research first, opinions second

Good UX starts with evidence, not guesswork. We talk to your team, look at your analytics, review how customers actually use the current site or app, and where it makes sense, test with real users. Design decisions then rest on what your Sydney customers do, not on what anyone in the meeting room prefers.

Prototypes you can click before we build

Before a line of code is written, you click through an interactive prototype of the key journeys: finding a service, requesting a quote, buying a product, signing in. It is far cheaper to change a prototype than a finished build, and it means everyone signs off on exactly the same thing.

Interfaces that hold up as you grow

We design with a proper component library and design system, so new pages and features stay consistent instead of drifting over time. Whether we build it ourselves or hand it to your developers, the system keeps your product looking and behaving like one coherent thing.

Frequently asked
questions

Do you run UX workshops in person in Sydney?

Yes. We are based in Penrith and can run discovery workshops and user sessions in person across Greater Sydney, or online if that suits your team better. Most of the design work itself happens remotely either way.

Can you redesign the UX of an app or site we already have?

Yes. We start with an audit of where users struggle and drop off, prioritise the fixes by impact, and redesign those journeys first, so you see improvement without a full rebuild.

What do we get at the end of a UX and UI project?

Research findings, user journeys, wireframes, a clickable prototype, final high-fidelity designs and a design system in Figma, ready for development. If we are building it too, you get the finished product.

Do you design for accessibility?

Yes. We design to WCAG accessibility guidelines as standard, with readable contrast, clear focus states and sensible structure, because an accessible experience is a better experience for everyone.
